Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The The invention relates to a device according to the preamble of the claim 1.
Es ist bekannt im Bereich des Bogentransports zwischen Druckwerken einer Druckmaschine und einer Auslegeeinrichtung Inspektionssysteme anzuordnen. Hierbei werden im Allgemeinen Kameras den Bogen führenden Elementen wie endlosen Kettenfördersystemen oder Bogentransporttrommeln zugeordnet. Entsprechend der Produktionsweise von Druckbogen werden Inspektionssysteme sowohl der Bogenvorder- als auch der -rückseite zugeordnet, wobei es notwendig ist, die Druckbogen für die Abtastung in definierter Lage bereitzustellen. Hierzu sind verschiedene Möglichkeiten bekannt.It is known in the field of sheet transport between printing units a printing press and a delivery device to arrange inspection systems. In general, cameras are leading the way here Elements like endless chain conveyor systems or sheet transport drums assigned. According to the mode of production of signatures, inspection systems of both the front and as well as the back it is necessary to include the printed sheets for the scanning to provide in a defined position. There are various possibilities for this known.
Einerseits
kann ein Druckbogen an einem Kettenfördersystem geführt und
in diesem Fall eben ausgespannt werden. Eine derartige Vorrichtung
mit einem Inspektionssystem an Druckmaschinen ist in der
Eine andere Möglichkeit besteht darin, Druckbögen in einer Druckmaschine während des Transports auf einer Bogentransporttrommel zu vermessen. Dabei können die Druckbögen mittels pneumatischer Mittel auf der Bogentransporttrommel straft gehalten und mittels einer der Bogentransporttrommel zugeordneten Aufnahmeeinrichtung in definierter Lage vermessen werden.A different possibility It consists of printed sheets in a printing press during transport on a sheet transport drum to measure. there can the printed sheets punctures by means of pneumatic means on the sheet transport drum held and assigned by means of a sheet transport drum Recording device are measured in a defined position.
Schließlich ist
aus der
Die gezeigten starren Bogenleiteinrichtungen neigen dazu, Druckfarbe von dem hochschlagenden Ende des aus dem Druckspalt auslaufenden Druckbogens anzunehmen. Dies erzeugt einerseits Verschmierungen und durch Farbrückspaltung auch generell Störungen im Druckbild.The shown rigid sheet guiding devices tend to print ink from the high impact end of the expiring from the nip printing sheet to accept. On the one hand, this causes smearing and color splitting also in general disturbances in the print picture.
Die Aufgabe der Erfindung ist daher, in einer gattungsgemäßen Vorrichtung bei exakter Bogenführung zur Abtastung von Druckbögen, Störungen durch Farbverlagerungen während des Bogenlaufes in der Druckmaschine zu vermeiden.The The object of the invention is therefore, in a generic device with exact bowing for scanning printed sheets, Disturbances by Color shifts during to avoid the sheet run in the printing press.
Die gestellte Aufgabe wird mit den Merkmalen des Patentanspruches 1 gelöst.The Asked object is with the features of claim 1 solved.
In vorteilhafter Weise wird durch den Einsatz einer oder mehrerer zonaler Bogenführungseinrichtungen im Bereich nach dem Druckspalt des letzten Druckwerkes an dem entsprechenden letzten Druckzylinder eine Verbesserung der Abtastbarkeit von Bogen erzielt.In Advantageously, by using one or more zonal Arc guiding devices in the area after the nip of the last printing unit to the corresponding Last printing cylinder an improvement in the scanning of sheets achieved.
In vorteilhafter Weise kann die Bogenführung ergänzt werden durch Stellmittel zur Positionierung der zonalen Bogenführungseinrichtung, sowie durch Blas- oder Ansaugmittel.In Advantageously, the bowing can be supplemented by adjusting means for positioning the zonal sheet guiding device, and by blowing or aspirating agent.
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispieles näher dargestellt. Die zugehörigen Zeichnungen zeigen inThe Invention will be described in more detail below with reference to an embodiment. The associated Drawings show in
